The company will also show the StreamStacker-HD e2 (e-squared) codec, which can carry multiple programs with surround sound, audio metadata, and associated auxiliary data. The latest version carries Dolby-compatible metadata, plus it can generate and regenerate metadata in both the encoder and decoder, allowing simple editing or correction of parameters. A GPI-controlled soft-bypass mode allows installation of the system in series with other coding systems, such as Dolby E, to support legacy content.

The Linear Acoustic LA-5180 audio metadata frame synchronizer and generator supports both DTV transmission and remote or studio production. The unit accepts audio metadata via a standard RS-485 serial input or as delivered inside the VANC space of an HD-SDI stream. The LA-5180 can also be used as a standalone generator, with eight presets for both Dolby E and AC-3 metadata.
